HANQI recently completed the delivery of an integrated nitrogen removal project for ethylene wastewater at a petrochemical enterprise, with the system now running stably. Throughout the project execution, HANQI worked closely with the client team to overcome operational challenges including significant water quality fluctuations and stringent treatment requirements.

In response to on-site water quality variations, HANQI's R&D and engineering teams maintained a long-term presence at the facility. With careful guidance and strong support from the client's relevant departments and leadership, they carried out continuous process and parameter optimization. Through repeated testing and adjustments, the system’s adaptability and treatment efficiency were steadily improved. Effective communication was maintained throughout the process, with the client providing crucial support in technical coordination and on-site cooperation. The project was successfully delivered as scheduled, achieving stable system operation and consistently meeting effluent standards.

HANQI sincerely thanks the client for their trust and collaboration. We remain committed to the field of challenging industrial wastewater treatment, practically advancing technology application to provide reliable and sustainable solutions for our customers.
